Definitions

  • the present invention relates to a combination of a gasket and an engine part, the gasket having an auxiliary attaching mechanism, so that the gasket can be fixed to a required portion on one of engine parts where the gasket is permanently installed.
  • a gasket is installed between two engine parts, such as between a cylinder head and a cylinder block, between a cylinder head and a manifold and so on, for sealing therebetween.
  • positioning pins are generally formed on the cylinder block, while the gasket is provided with positioning holes.
  • the gasket can be properly positioned on the cylinder block by engaging the positioning holes of the gasket with the positioning pins on the cylinder block.
  • a gasket attaching surface of the cylinder head may not face upwardly.
  • the gasket attaching surface is oriented sidewardly or downwardly.
  • the manifold gasket can not be simply located on the cylinder head, or on the manifold. Therefore, when the manifold gasket is installed, the manifold gasket must be held by a person installing the manifold.
  • the cylinder block is provided with the positioning pins for aligning the gasket and the cylinder head.
  • FR-A-1001 961 describes a plastic material gasket having attachment devices. However the attachment devices are not capable of retaining the gasket on an engine part when orientated downwardly.
  • DE-U- 1 945 026 describes a gasket having curved spring clips which hold the gasket to an exhaust pipe flange but which do not accurately align the gasket and exhaust apartures together.
  • US-A-4 650 227 describes a gasket for a hose connector wherein spring clips are provided which engage a smooth cylindrical surface by friction alone, the clips having resiliency only and no mechanical locking engagement with the part to be sealed.
  • one object of the invention is to provide a combination of a gasket with an engine part, the gasket having auxiliary attaching mechanism, wherein the gasket can be attached to an appropriate position on one of engine parts for installing the engine parts together.
  • Another object of the invention is to provide a combination of a gasket and an engine part as stated above, wherein the gasket can be securely attached to the engine part even if the engine part is moved.
  • a further object of the invention is to provide a combination of a gasket and an engine part as stated above, wherein the gasket can be easily and economically manufactured.
  • a combination of a gasket and an engine part the gasket being adapted to be attached to the engine part which has a flange or a connecting position extending from a flange for installing the gasket
  • the gasket comprising: at least one plate (12; 20, 21; 30, 32; 41) for constituting at least a part of the gasket, and having an outer edge; at least two auxiliary attaching devices (15; 24; 35; 46) of resilient metal connected to the outer edge of the plate and projecting outwardly from the plate to engage said engine part, said resilient metal member having a straight portion extending from the outer edge of the metal plate (12; 20, 21; 30, 32; 41) and a projection (16; 25; 47) attached to the straight portion to extend towards the engine part (M; M'); said combination being further defined in that said straight portion of the gasket has a length substantially the same as the flange or connecting portion thickness to enable, said projection (16; 25; 47) and plate (12; 20, 21; 30, 32; 41) of the gasket to
  • the gasket Since the gasket is firmly attached to one of the engine parts, such as a cylinder head or a manifold, even if a gasket attaching surface of the engine part does not orient upwardly, the gasket does not fall from the engine part.
  • the gasket can be situated properly between the two engine parts and can be securely fixed therebetween by regular connecting means, such as bolts.
  • the auxiliary attaching devices need not be removed after the two engine parts are connected together.
  • the metal plate includes at least one first hole to be sealed, and at least two bolt holes situated near the first hole.
  • the auxiliary attaching devices are located away from the bolt holes so as not to affect bolts inserted into the bolt holes.
  • the auxiliary attaching devices may be formed at the connecting portion.
  • the auxiliary attaching device is formed of a resilient metal member, engaging the engine part.
  • the two metal members hold the engine part therebetween to locate the gasket on the engine part.
  • each metal member includes a projection facing the engine part when installed. As a result, the projections firmly engage the engine part.
  • the gasket may be formed of one metal plate, or a plurality of metal plates for constituting a steel laminate gasket. Also, the gasket may be formed of one metal plate laminated with other gasket material, such as a binder (rubber or resin) with fibers or graphite.
  • the metal plate may be a core of the gasket or may not extend the entire area of the gasket.
  • the gasket A is a manifold gasket, which is installed between a cylinder head (not shown) and each manifold pipe Mp of a manifold M.
  • the gasket A is formed of two outer metal plates 10, 12 and a middle member 11, and includes a central hole 13 and two bolt holes 14.
  • the central hole 13 corresponds to an inner diameter of the manifold pipe Mp
  • the bolt holes 14 correspond to bolt holes Hb at a flange F of the manifold M.
  • the metal plate 12 is provided with two engaging members 15 extending outwardly from the metal plate 12.
  • Each engaging member 15 includes a projection 16 extending toward the central hole 13. The projections 16 engage edges of the flange F when the gasket A is installed on the flange F.
  • the metal plates 10, 12 may be any kind of metal, but the metal plate 12 has resiliency to provide resiliency at the engaging members 15. Because the engaging members 15 have resiliency, the gasket A can be securely attached to the flange F of the manifold M when installed.
  • the middle member 11 is formed of a gasket material including a binder and organic fibers.
  • the gasket material must be strong against heat.
  • the metal plates 10, 12 and the middle member 11 are joined together by glue. However, the metal plates 10, 12 and the middle member 11 may be joined by any means, such as spot welding between the metal plates 10, 12, a grommet covering the metal plates 10, 12 and so on.
  • the gasket A When the gasket A is installed on the flange F of the manifold pipe Mp of the manifold M, the gasket A is simply pushed onto the flange F. The projections 16 engage the flange F to prevent the gasket A from disengaging from the manifold pipe Mp.
  • the gasket A is secured to the flange F of the manifold M. Therefore, even if a gasket attaching surface of the cylinder head orients sidewardly or downwardly, the gasket is securely attached onto the flange F and is moved together wit the manifold M to be installed between the flange F and the cylinder head.
  • the gasket A is attached to the manifold M. However, if there is a flange near the gasket attaching surface of the cylinder head, the gasket A may be attached to the cylinder head.
  • the manifold M is fixed to the cylinder head by bolts (not shown) while the gasket is attached to the cylinder head or manifold by the engaging members.
  • Figs. 3 and 4 show a second embodiment B of a combination of a manifold gasket and an engine part according to the invention.
  • the gasket B is designed to be installed on a manifold M' having connecting portions Mc between the flanges F of the manifold pipes Mp'.
  • the gasket B is made of one metal plate, and is formed of a plurality of gasket portions 20 and connecting portions 21 for integrally connecting the gasket portions 20.
  • Each gasket portion 20 includes a hole 22 corresponding to a hole of a manifold pipe Mp' and two bolt holes 23 for bolt holes Hb'.
  • Engaging members 24 with projections 25 are formed at the connecting portions 21 to face with each other.
  • the gasket B When the gasket B is installed on the manifold M', the gasket B is aligned with the manifold M' and is pushed so that the engaging members 24 hold the connecting portions Mc. As a result, the gasket B is securely attached to the manifold M'.
  • the gasket B operates as in the gasket A.
  • Fig. 5 shows a third embodiment C of the gasket of the invention.
  • a plurality of the engaging members 24 is connected by the connecting portions 21, but in the gasket C, two gasket portions 30 are integrally connected by one connecting portion 32.
  • the gasket C is formed of one metal plate, and each gasket portion 30 is provided with a hole 33 and two bolt holes 34.
  • Engaging members 35 as in the engaging members 15 and 24 are formed on the gasket portions 30.
  • the gasket C is installed in a manifold similar to the manifold M shown in Fig. 2. In the gasket C, since the two gasket portions 30 are connected together, handling of the gasket portions 30 is facilitated.
  • Fig. 6 shows a fourth embodiment D of the manifold gasket of a combination according to the invention.
  • the gasket D is a steel laminate gasket and is formed of an upper plate 40, two middle plates 41, 42 and a lower plate 43.
  • the plates 40, 41, 42, 43 have central holes 44 and bolt holes 45.
  • the middle plate 41 includes engaging members 46 with projections 47, and the middle plate 42 includes two beads 42a around the hole 44 for sealing therearound.
  • the lower plate 43 has two flaps 48 turning over the upper plate 40, so that the plates 40, 41, 42, 43 are connected together without spot welding.
  • the gasket D operates as in the gasket A.
  • the gasket is provided with the engaging members, which engage an engine part that the gasket is installed. Therefore, when the gasket is installed between the engine parts, the gasket is attached to one of the engine parts. Consequently, the gasket can be easily installed between the two engine parts regardless the location or an angle of a gasket attaching surface of the engine parts.
